Ring size guide
Find your size at home in a few minutes, then match it to Indian, US, UK or European sizing.
Two easy ways to measure
1. Measure a ring you already own
Choose a ring that fits the finger you plan to wear the new ring on. Measure the inside diameter, edge to edge, in millimetres, and find the closest diameter in the chart below.
2. Measure your finger
Wrap a thin strip of paper or string around the base of your finger. Mark where it overlaps, lay it flat and measure the length in millimetres. That is your circumference; type it into the size finder.
Tips for an accurate size
- Measure at the end of the day, when fingers are largest.
- Avoid measuring when your hands are cold.
- If your knuckles are larger, make sure the ring will slide over them.
- For wide bands (over 4 mm), choose half a size up.
- Between two sizes? Choose the larger one.
